So, I just purchased a set of New FAG wheel bearing (made in Germany) so I can install a set of the later (74-89) 911 rear hubs on my 914 control arms.
I saw a few you tube videos about how the bearings for the Boxster where being shipped with little to no grease in them. I figured before I install them to check the grease. Well sure enough one side had little grease and the other side had very little to no grease on the bearings. I should've taken a few pics but didn't have my phone handy. I still have another new bearing to inspect so I'll take pics of that one. I'm sure it will be the same way. Now to go pick up some grease and repack them. So if anyone of you out there plan on replacing your rear bearing I would inspect them. Here's a handy video which shows how to do this. https://www.youtube.com/watch?v=l9P1R2clGAU |

(IMG:style_emoticons/default/stirthepot.gif) The other thing to keep in mind for you guys tracking vehicles or racing is that high lateral G's for sustained periods are typically outside the production vehicle operating envelope (including Boxter's and 911's). High lateral loads force the load in the bearing raceway diagonally upward on the bearing race vs. the normal downward force from gravity. This puts more pressure & load on the thinner portion of the bearing raceway up near the square edge. In extreme cases, the ball to race loads can be moved up high enough that you'll begin to deform the raceway and this begins a death spiral of pitting and material deformation in the raceway and debris circulating in the bearing. Bottom line - bearings are a consumable item if racing. Do proper maintenance before failures occur. Higher temp grease will help delay this but it will eventually occur due to the way the load is being applied up high on the raceway and for the extended duration that it is applied during racing or track use that the bearing wasn't designed for. See video below at the 0:56 second mark. Note how high up on the raceway the damage is. https://www.youtube.com/watch?v=-A5kf5pXl4w |
